Well, the truck is still surging a little here and there.
After driving for awhile, it'll pop codes P0202, P0204, P0206, P0207
(Which means injector control circuit malfunction). I'm running the FMS
21# injectors in the 4.7L. Checked with the scan tool and the long term
fuel trim while on cruise control at 70MPH is about -15% to -18%. I've
seen it peaking at 20% or so as well. Is this too high? I have the Leach
PCM, should I have him cut back on the fuel a little?
I appreciate your help. I'll pull the freeze frame data in the morning.
Thanks
william
